There is a large number of academic studies looking at the relationship between divorce rates and divorce law in a range of jurisdictions. You can always find one or two studies that will be outliers, particularly from the United States where there are aligned researchers. The strong message from the consensus of academic opinion is that there is no relationship between the substantive divorce law and divorce rates. The paper by Libertad González that you reference clearly said that procedural changes can have an impact on divorce rates, not the substantive law. If you look at our law, we have fault. Of all divorces, 60% or so are proceeding on fault. They will all get through. Fault is not a bar to achieving a divorce at all.
